Who Will Replace Putin in 2018 (Or 2017, In Case of a Revolution)?

Maltsev said: “The first to be imprisoned will become a President? He was arrested yesterday; Navalny was locked already a few times and I did not check if Maltsev has been ever imprisoned. They both do the same job: they reveal corrupted schemers of top Russian politicians and fight for better future. Here is a half-year old video with an extract of their meeting. BTW, “051117” is a date of a new era (revolution?) in Russia according to Maltsev.
So, Maltsev or Navalny?
